Heat is to be removed from a reaction vessel operating at 75°C by supplying water at 27°C and 0.12 kg/s through a thin-walled tube of 15-mm diameter. The convection coefficient between the tube outer surface and the fluid in the vessel is 3000 W/m2 K. (a) If the outlet water temperature cannot exceed 47°C, what is the maximum rate of heat transfer from the vessel? (b) What tube length is required to accomplish the heat transfer rate of part (a)?

Question
Transcribed Image Text:Heat is to be removed from a reaction vessel operating at
75°C by supplying water at 27°C and 0.12 kg/s through a
thin-walled tube of 15-mm diameter. The convection
coefficient between the tube outer surface and the fluid in
the vessel is 3000 W/m2 · K.
(a) If the outlet water temperature cannot exceed 47°C,
what is the maximum rate of heat transfer from the
vessel?
(b) What tube length is required to accomplish the heat
transfer rate of part (a)?
